Line connects control centre, and display screen is fixed together with through hole I, and button I is embedded in through hole II, and button II is embedded in logical
In hole III, cover device is made up of pressure sensor, containment vessel, receiver and transmitter, and containment vessel is surface mounted to few two
Individual pressure sensor, pressure sensor connects receiver by electric wire, and receiver connects transmitter, receiver and biography by electric wire
Defeated device is fixed on the inside of containment vessel.
Described control centre is into power supply passes through electric wire linking parsing device, analysis by power supply, analyzer and singlechip group
Device connects single-chip microcomputer by electric wire, and single-chip microcomputer connects display screen by electric wire.
Described shell I pastes one layer of fluid sealant with the junction of shell II.
Described protective cover is connected adhesive tape with the junction surrounding of through hole I.
The material of described protective cover is safety glass.
The present apparatus is not in that header field withstands drive, the occurrence of another portion fails to touch drive, it is ensured that
The balance of hydraulic prop pressure, does not interfere with hydraulic prop service life, has ensured the life security of staff, it is not necessary to coal
The hydraulic prop quantity increase that ore deposit enterprise uses in drive, production expenditure also greatly reduces, and does not interfere with the turnover of staff.
